For fast reliable results there's no instrument in the world that c a n match our's.The JY-48 Plasma Simultaneous Elemental Analyzer c o m b i n e s the operating speed and simplicity of a computerized direct reading spec­ trometer with all the advantages of Inductively Coupled P l a s m a (ICP). Built and backed by one of the oldest n a m e s in spectroscopy, the JY-48 can analyze up to 48 elements at one time in a wide variety of samples, including water, oils, petroleum, geologicals, biologicals, and ferrous and n o n ferrous metals.

With the JY-48 comes all the sup­ port you'll ever need. Our installation and field service, software, and tech­ nical applications laboratories are unsurpassed. And if you're interested in Sequential ICP Elemental Analyzers, Instruments SA is there too, with both a scanning monochromator accessory to the JY-48, and the J Y-38 Sequential P l a s m a Spectroanalyzer.
